What the less work rotor ?

[Freak Rabbit]

I gonna buy 2x 330mm Mercedes C230Sport. how many material i need to remove from the caliper ears for the best fit ???

330mm: W203 (2000 - 2007) Mercedes Benz C230 Sport (must be the sport version, the non-sport does not have the larger rotors). The only downside is that these rotors came cross-drilled from the factory and therefore all replacement rotors will be the same.
Part numbers- Centric: 121.35086, EBC: 725, Raybestos: 980521
Caveats- center hub diameter must be increased by 1mm, lug bolt holes must be drilled out to 14mm, rotor offset not perfect- live with it or change caliper/knuckle thickness to center caliper on rotor


the ears being drilled off was the e500 rotors if i recall

[blitz2190]

quick question, has anyone tried the b8 s4 rear rotors for the 17z? they are 330x22 compared the the stock x25 does anyone know what the Mercedes Benz C230 Sport offset is?

Anything smaller than 30mm thick and you can pop the pistons off the caliper.

22mm thickness is atrocious. Can you please explain to me why you're still looking for new options? I mean, I'm all for a rotor that requires zero modification without compromises, but just buy Volvo rotors and be done with it. Less than five minutes to modify them and you have a proper 32mm thick disc with a good vane design.

^Thissssss.

MB ML320\350 rotors fit well too and are 32mm. Just have to open the bore a tiny bit.

Can anyone confirm if this is the correct p/n for rebuilding 18z (350mm) calipers? CENTRIC 14335037

Not seeing the point. Why not just use the proven V70R rotors...

Dont you also need to machine the caliper ear with the V70R rotors as per post #107 and post #119?

I have the Q5 345mm Brembo's on my car and I'm debating going the 6 pistons rout since I have two sets of 17Z in stock.

Wait what? 17Z is better?

Despite having 4-piston 345mm Brembo, you still want more? Why? Just to try something else and see if it feels different?
Maybe will be lighter (smaller rotor, 345mm --> 330mm)

LE: Oh, and just as a nice info, the 321mm B7 rotors are heavier than the Volvo 330mm rotors. Also, the 4 pot calipers are lighter than the B8 ones. So you have larger brakes and less weight.

I've held Centric Premium High-Carbon B7 321mm rotors before, and they seemed heavy.

I didn't touch the pad pins or mounting ears on my car. The outboard pins are super close to the rotor, but once the rotor is sandwiched against the hub with the wheel bolted on, there's no contact (on my car, at least). It may be worth grinding a few millimeters off the outer pad pins just for peace of mind, but I wouldn't touch the mounting ears. No need.

And going from the 345mm Brembo to 17Zs would be a downgrade IMO. Unless you don't care about fade resistance (though truthfully, 17Z are more than fine in this regard for any sort of street use in my experience).

BTW, post #107 and #119 feature the later four-piston Touareg 1LE caliper, not normal 17Z. There is a design difference in the body of the caliper. The regular 17Z has no issue with it contacting the casting of the caliper. The only potential concern point with normal 17Z are the outboard pad pins.

Got it! I should grab a spindle and play with it.

I just really like the look of the 17/18/19z over the Q5's. If I do install a set on one of my cars it will probably be on the B6 which as the 320 Q5 Brembos.

Dont want to beat a dead horse but @LINDW4LL just to be sure, the V70R wil be centered in the caliper once mounted?

I'm only asking because both the 1LE and 17Z share the same rotors right? I dont understand why is the V70R rotor offset in the caliper when in a 1LE but its centered on the 17Z?

Wont be like that:

[vvenom800tt]

For 17z you need to use MB GL320 rotors (diesel model) i think its 07-08.

Its the only rotor that fits withough shaving the caliper. Also stud holes are 14mm

ok i asking for information and not to confuse anyone about this. but i have 18z calipers that i plan to mount on my cabby. i already have the b6s4 setup on my car and i ran into this bit of info can anyone verify that i can use my existing rotors 345mm or is total bs

I think the 345mm Audi rotor works, just use 330mm pads. So they dont overhang the rotor.

The B6/B7 S4 rotor offset is not at all correct for 18Z. A few have done it, but have to modify ears. Just go ML55 route.

You're correct that the 1LEs and 17Z have the same fitment. The rotor is not absolutely PERFECTLY centered, but it's damn close, and the 17Z casting does not interfere like with the 1LE caliper above. You can see the rotor sits a tiny bit more outward in the 1LE pic (and thus why its the outboard pad pins are the potential issue on the 17Z/v70r), but we're talking a minuscule deviation from center.

I've run 18Z with B6 S4 Avus(18*8 ET45 with 10mm spacers), rep Gallardo(18*8 ET46) and currently on COX CS-9(19*9 ET42), all their specs were in safe range, which means no issue at all!

I got a B6 friend using the B8 S4 brakes, now he's looking for more powerful brakes lol

Awesome thanks for the info was unsure about the fitment but got them cheap !

I don't go to the track so hopefully the s4 will be good enough for the street

So I can use the Volvo rotors with the 17z without machining the caliper ears? Need to know so I can order rotors.

[TMeschke]

Unfortunately not. I went the route of Volvo V70R rotors with 17Z calipers. I had to machine the lug holes larger, to increase the diameter of the lug pattern, and I had to machine about 3mm off the mounting tabs for the calipers to sit centered over the rotor.

[TMeschke]

I figured I'd post some pictures and info of the swap I did a while back. There are are fair number of things I wish I did differently, so I thought that some people could learn from my mistakes.

I pulled the Brembo 17Z calipers off a scrapped 2004 Touareg. As seen below, they weren't looking the best when I got them.



I pulled out all of the pistons (which was a pain in the ass) and prepped the calipers for paint. I also decided to clean up the hardware to make it look nice. One of the bleed valves had all the threads stripped off, so it had to be replaced. The replacement valve was cheap, and worked better than the ones that came on the caliper. Mistake number 1 was taking the time to restore the old bleed valves instead of just buying new ones. The new bleed valves are cheap, easy to find, and worked better than the originals.







The rotors I decided to go with were for a Volvo V70R. The center bore is the correct size, but the lug holes need to be drilled out larger to fit the Audi bolt pattern. Much to my surprise, I also found that the calipers would not sit center over the rotors. After measuring it out, I determined that the mounting tabs needed to be machined down about 3mm.

For the mounting hardware, I decided to put together my own set instead of buying a set that is made specifically for this swap. That was mistake number 2, it ended up being about the same price as a pre-made set, and the hardware I used has made it a huge pain in the ass to take the calipers on and off. After further test fitting and confirming that everything would work properly, I was ready for paint.

Here comes mistake number 3. I decided to use G2 caliper paint, since I didn't want to spend the money on powder coating. While the calipers came out looking fairly good initially, the paint chips off fairly easily. About a year in, I already need to repaint the calipers, and will definitely powder coat them this time. Take my advice, do it right the first time around. Powder coating really isn't that much more expensive, and it will last much longer. I found some Brembo vinyl decals on eBay for pretty cheap, and they have worked terrific; it cleans up nice and still hasn't pealed at all. I replaced all the o-rings and dust boots, and was ready to get the calipers mounted.







The brakes have been working terrific since I got them installed. Since I used the stock brake booster and master cylinder, the brakes aren't extremely responsive on the top of the pedal travel, but they will definitely bite hard when you want them too. I prefer having them this way, so I'm not getting sent through the windshield every time I tap the brakes. Even though I ran into some issues and had some regrets, the swap went fairly well, and I'm happy I did it.

Let me know if you have any questions for me. I'm sure I left out some details somewhere.

[vvenom800tt]

For the 12977392784 time.

For the 17z caliper, you need to use an 07-08 ML320 diesel rotor.

Just buy a pair of 2mm thick washers and space the caliper back. Fits perfect.

Quit fucking spreading misinformation about tbe volvo rotors fitting without modifying the calipers

All you need to do on this rotor is open the center bore 1mm.

And its 32mm thick, which is the correct thickness.

Then why dont you drag your ass over to my car, take a front wheel off, unbolt my caliper (which is perfectly centered might i add) and watch the washers drop to the ground.

You have Brembo 17Z calipers with Volvo V70R rotors on a B6 A4, correct?

No, he was talking about ML320 rotors.

Alternatively the O1E caliper with the v70r fits perfectly once the washers are used to space the caliper back.

I plan on using the same rotors as you. Seems to me that that will gain 5mm of clearance vs. grinding the ears on the calipers. Do you happen to know if 17x8 ET47 wheels will work over the 17z calipers?

I can run my stock B6 sport wheels with a spacer and it clears plenty (winter wheels). They are 17x7.5 ET45.

Depending on the design it might be a little tight. You'll probably need a spacer. I run 15mm with those winters.
I used a washer about 2mm thick between the caliper ear and the upright to space the caliper enough to sit perfectly flush.
